IVIM diffusion parameters and ADC values were quantified in 79 HCCs and liver parenchyma in 46 patients at 3T. D (true diffusion coefficient), PF (perfusion fraction) and ADC were all significantly higher in HCC compared to cirrhotic liver parenchyma. There were also significant correlations between D/PF/ADC and tumor necrosis in treated HCCs. There were significant differences in D/ADC and no significant difference in PF between necrotic components and viable components. The ADC value in the necrotic lesion is more affected by the value of D and less affected by the value of PF.
